Do I need to hook my new battery to a battery tender EVERYDAY
I don't ride it?? I took my bike in this weekend for a 600M service and they had to replace the faulty old battery with a new one (free of charge!!). Just wondering if I badly need to buy a battery tender right away.

 

That is why the battery tender comes with the adapter that you put on the batter permanantly and then just quick hook up. Over the winter, it doesnt hurt to just leave it hooked up. Otherwise, no, you dont need it on every day. I dont even use mine anymore. I start it and let it come to temp once a month/ or ride depending on the snow fall and havent had a problem with it.
